"Show all" default selection in appointments is not fetching all users appointments

[nihal467]

Describe the bug

• When we open the appointments page from the patient details page, even though by default "show all" is selected, the calendar is not prefilling the available dates of practitioner
• When there is no practitioner available in the facility, the dropdown still shows "select practitioner" in the placeholder

2. See error

Expected behavior
